October 2018, Seeds of Sustainability, Rich Harrison, Registered Landscape Architect, currently
works for Metro Blooms, which is a non-profit promoting gardening and beautifying our community.
They, along with the Blue Thumb, advocate planting for clean water.
He began this presentation with a little background to set the stage. Only 3% of the earth’s water is fresh.
Of this amount, 90% of the fresh water is locked in glaciers with only 0.007% of fresh water available
With regard to Minnesota, in 1816 there were 18.6 million acres of wetlands in the state. Presently there
are 9.3 million. We have more shoreline than California, Oregon and Hawaii combined. There are three
major watersheds in Minnesota: Mississippi, St Louis and Red River. We are all connected to our
streams, lakes and rivers.
In Minnesota 40% of our waters are impaired. Because of this and other factors, we must be aware of the
consequences of urban storm runoff which frequently goes right to a river or stream and contains
nutrients, salt, oil, and heavy metals. Climate change has only exacerbated the problems with an increase
in extreme rainfall events which means that higher volumes of water are moving through our landscape with a subsequent increase in storm damage and more of the aforementioned materials released.
There are some Metro Bloom programs which are trying to retard runoff
1. Neighborhood of Rain Gardens. In partnership with the Conservation Corps, 1200 rain gardens
have been installed in Minnesota and Iowa. The average garden is 130 square feet which
translates into approximately 150,000 square feet of urban habitat.
2. Blooming Boulevards: Through this program boulevards are reshaped as ash trees are being
removed on 37 properties. Typically the boulevards are excavated after the removal of the trees,
by loosening the heavily compacted soil and creating swales. This allowed water to collect,
instead of running off the boulevard, and should benefit any future tree planting.
3. Blooming Alleys: This project is focusing on the Lake Nokomis watershed where 60% of the
properties drain to the alley. By working with community members to design and install visually
appealing practices such as rain gardens, pervious pavement, and native plantings; the goal is to
reduce the amount of runoff and pollution that would otherwise flow down the alley and into
storm drains and transform alleyways into habitat corridors that attract pollinators.
4. Additional organization efforts include Field Maintenance, Sustainability Training Plots,
Commercial Projects, and Workshops. Since 2007, 6,832 property owners have attended various
workshops. There are approximately 15 workshops per year with 33% on installing rain gardens.
There are many things homeowners can do to reduce runoff and the amount of contaminants therein:
1. Keep grass clippings and leaves out of the street
2. Adopt a drain
3. Clean up pet waste
4. Avoid pesticides and fertilizers
5. Raise your mower blade (3” as the minimum height)
6. Water with intention. Don’t set and forget. Don’t water between 10am and 6pm
7. Shovel walks and driveways promptly, using grit if needed for traction. Avoid using excess salt.
8. If there is a concentrated flow in your yard, put in a rain garden
Meeting Notes

9. SOS Stop oversalting!!
Tools for a resilient lawn
1. Install rain barrels
2. Redirect runoff
3. Create swales and creek beds
4. Install channel drains
5. Install permeable pavement
6. Reintroduce native trees and plants
7. If you are not actively using an area it shouldn’t be
lawn.
8. Try not to have so much Kentucky bluegrass. To
change the mix, cut grass very short, then seed with
asters, and rake in for soil contact. Asters can be
mowed and will still bloom. Ivory sedge is also a good shade ground cover
9. Restore and support healthy soil by
- Mulching leaves in place in the fall Let them be where they are – this is where pollinators
overwinter
- Mixing shredded leaves or compost into the soil
- Using ground covers
- Planting deep-rooted native plants
When looking at designing your yard, keep in mind the following objectives:
1. Have a mixture of grass and shrubs.
2. Have a mixture of native plants. Try to have three flowering plants for each season (spring,
summer, fall) for the pollinators.
3. Plant in masses, having drifts with variable heights.
4. Think about where the focal point is and where one will be viewing this area viewing.
5. When installing rain gardens:
a. The bottom should be perfectly flat
b. Side-slopes should be 1:3
c. Put double shredded leaf mulch on the bottom
d. Have clean edges
e. Leave some bare spots for native bees to nest
f. Some suggested natives include cup plant, bee balm, coneflower, goldenrod
November 2018, From the ground up…..tips on pruning and timing”, Jason S. Pruett,
M.A., Treehugger Tree Care, Inc., ISA Certified Arborist MN-4226A, CTSP, TRAQ, EHAP, MNCPA. (Editor’s Note: Below are excerpts from the Jason Pruett’s slide show given that evening. I was unable to attend,
so the highlights from the power point presentation were copied directly with minimal interpretation of the
contents which would have been more fully elucidated based on the speech itself had I attended.)
The topics on pruning included the following:
Sanitize your tools. Suggested products are shown here.
If bleach is used dilute with 1 gallon of bleach to 3 of
water. Time this job. That is, “Don’t prune in April,
May, and June”. Prune now, but not when it is wet.
Suggested native species with lower
vulnerability to climate change
Trees: Red Buckeye, Ironwood, Bur Oak,
Linden, Scarlet Oak, Kentucky Coffee
Tree, Eastern Red Cedar, Yellow Wood?
Bushes: Serviceberry, Blue beech,
Pagoda dogwood, Witch Hazel,
winterberry, raspberry, ninebark,
nannaberry, Red twig dogwood, black
chokecherry, Dwarf bush honeysuckle

Use the right tools.
Examples are shown in the
slide to the right.
Tips on pruning:
Ed Gilman: “When in doubt, prune it out!”
Katherine Aby: “You can only cut it out once, so punish the tree nicely.” “Make one
final cut!”
Treehugger: “If you own OR can manage the tree on an ongoing basis, then take your
time.” BE conservative.
If NOT….See Ed OR Katherine! Auxins, which are produced by the tree, promote stem elongation. They inhibit growth of lateral
buds and play a role in maintaining apical dominance (That is, in increasing the tree’s height or
width). Note that as long as sufficient auxin is produced by the apical meristem (main lateral), the
sub-lateral buds remain dormant. If the apex of the shoot is removed (by a browsing animal or an
arborist), the auxin is no longer produced. This will cause the sub-lateral buds to break their
dormancy and begin to grow. In effect, the plant becomes bushier. When a gardener trims a
hedge, they are applying apical dominance.
Branch Bark Ridge. Try to minimize the number of
cuts. Also try to cut the least amount of surface area
--- Think “less wounding of the cell covering”
When the branch collar is present, it is the best guide
for the final cut when removing a living branch.
How and where to cut. See below.
Compartmentalization (CODIT) - Compartmentalization of decay in trees:
Trees do not “heal.” They don’t have the ability to regenerate cells.
A way a tree protects itself is by slowing or preventing the spread of disease and decay by
